2.6.1 SGPLZU/SGPLZV/SGPLZR

1.

Function

Draws polylines in the U/V/R-coordinates. Specifies attributes at the same time.

2.

Call

CALL SGPLZU(N,UPX,UPY,ITYPE,INDEX)
CALL SGPLZV(N,VPX,VPY,ITYPE,INDEX)
CALL SGPLZR(N,RPX,RPY,ITYPE,INDEX)

Explanation of Parameters

N	(I)	The length of array UPX, UPY.
UPX, UPY	(R)	An array with length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the UC.
VPX, VPY	(R)	An array of length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the VC.
RPX, RPY	(R)	An array of length N. Gives the (X, Y) coordinates of points to connect to form the polyline in the RC.
ITYPE	(I)	The line type See. SGSPLT.
INDEX	(I)	The line index. See SGSPLI.

Notes

(a)

N must be larger than 2.

(b)

The ITYPE and INDEX specified here do not change the ITYPE and INDEX inquired by SGPLU, SGPLV, and SGPLR.
